This part of ISO 19014 provides guidance and a methodology for determination of performance levels required for earth moving machinery (EMM), as described in ISO 6165 after a hazard is identified by risk assessment. NOTE This series can also be used to assess the functional safety requirements of other off-road mobile machinery Hazard identification is determined by risk assessment (herein also known as machine control system safety analysis MCSSA) using the method described in ISO 12100 or by other means and is not covered by this document. If a sub-system is determined to be a safety control system (SCS), a Machine Performance Level (MPL) is allocated to that sub-system. NOTE The term MPL is used to describe the performance level required from a safety-related part of a control system. The M refers to machine and denotes Earth Moving Machinery covered by the scope of this document and is used to differentiate from other functional safety standards (e.g PL, AgPL, ASIL, etc) . For those controls determined as safety-related, the characteristics for architecture, hardware, software environmental requirements and performance are covered by other parts in this series. ISO 19014 covers the hazards caused by the functional behaviour of safety-related systems and excludes hazards arising from the equipment itself (for example, electric shock, fire, etc.) The principles of this standard shall also be applied to immediate action warning indicator intended to warn the operator of a possible hazard and requiring immediate action from the operator to correct and prevent such a hazard. . (e.g. vision systems, proximity detection systems etc) NOTE A normative list of immediate action warning indicators is included in Annex B Other controls that are not safety control systems (SCS), that do not mitigate a hazard or perform a control function and where the operator would be aware of a failure, are excluded from this standard (e.g. windscreen wipers, head lights, cab light etc.) NOTE 1 An informative list of safety functions is included in Annex E. NOTE 2 Audible warnings are excluded from the requirements of diagnostic coverage. This standard supersedes ISO 15998:2008.
